The Rumbler: The New Sound Of The KCPD

KANSAS CITY, Mo. – Inspired by low bass pumping stereo systems, the Rumbler is the newest addition to police sirens in Kansas City, Mo. It was created for urban environments and features two large bass speakers that can be heard and felt from inside cars and even buildings. The Rumbler, introduced in 2007, was designed to literally shake the streets.

Rumblers cost $400 per unit and will be installed in all new marked Kansas City police cars. They're among the first police departments in the country to use them.
